To ALijI WHOM 1T MAYcONCERN; t I Be it known that I, CHAUNCEY C. PARKER, of Brooklyn, in thecounty of Kings', and State of New York,

have invente`d,'made, and applied to use a certain new land useful Improvement in Cord-Pulleys for Shades, &c.;. and, I do hereby declare the 'following to be a full, clear, and exact description of the said invention, reference heingA had to the annexed drawing, making part of this specification, wherein- Figure l is a vertical section of said cord-pulley; and l Figure 2 is an elevation of the" same.

Similar marks of.r'eference denote the same parts. Cord-pulleys for curtain fixtures have heretofore been made with a spring, which yields or expands as the cord may slacken or tighten under atmospheriein'lueinces. They have, however, been constructed so as to have a very different appearance from the ordinary rack-pulley, and the cost of manufacture was enhanced. The nature of my said invention consists ina'pulley-s'lide having two arms atright angles to each othenone arm receiving the pulley and the other extending up within the coils of a helical spring contained in a sheet-metal case, which arm becomes the guideand sustains the pulley, allowing it to slide with but little friction as the cord may contractor expand.

In the drawings, a is the case, formed as a slottedcylinder, having the ears b b, by which it is attached in place. e is the helical spring within theease a, lept in place by lips turned over at the end of the case. d is the pulley or sheave set up'on the pulley-sli'dee that is extended up within the spring c in the form of apiu or arm,f, that acts to guide and sustain the pulley as it slides back and forth, and said armfprevents the pulleyslide binding in the case under the action of the cord to the shadeor curtain. The spring case and spring may` he cylindrical or more or less flattened.

What I claim, and desire to secure by Letters Patent, is-

The pulley-slide, formed with two arms at right angles to each other, one arm, e, receiving the pulley, and Athe other aim,f, extending within the coils of a helical spring, e, within the slotted case a., so that said armf becomes a guide to sustain the pulleybut allows its free motion, as set forth.

In witness whereof I have hereunto set my signature this, eleventh day of December, A. D. 1866.`
